Addi Click interchangeable needle sets are back in stock and better than ever with a redesigned carrying case. These have been insanely popular, and they actually keep getting better. The new and improved set includes the US5 tips, so you get all even sizes between a US4 and a US15, and three different lengths of the extremely pliable blue cord (24″, 32″ and 40″). There is also a connector piece which helps to either store stitches or combine your cords.
The Click tips require no tools to change; simply insert the cord deep into the tip, twist and release (think of the child proof lid on a pill bottle). The tips will remain secure until you change them. There are also “booster” packs available, if you need more cords or tips.
